The piece ends in mystification. Raines's insistence that no one told him about Blair's history of errors is no more satisfying or credible now than it was a year ago. And as for why Sulzberger canned him, that may remain a mystery forever, because Raines himself doesn't want to know. He writes that his biggest regret is that he didn't buck up the publisher and check his emotional temperature. But don't ask him to learn anything from the process. "Once the essential bond is broken on one side or the other," Raines writes, "the marriage is over. Anything else is just details."
